Yes, for a sequence database you can use optional arguments to
the efetch command, see:

Quote:

seq_start - First sequence base to retrieve. The value should be the
integer coordinate of the first desired base, with "1" representing
the first base of the seqence.

seq_stop - Last sequence base to retrieve. The value should be the
integer coordinate of the last desired base, with "1" representing the
first base of the seqence.
